DANIEL WILDE,4 F WASHINGTON, IOWA.

STEAM-GENERATOR.

SPECIFICATION formingl part of Letters Patent No. 275,449, dated April 10, 1883.

Application filed August 1882. (No model.)

boilers, whether vertical, horizontal, or locomotive, and may be applied to either stationary or semi-portable boilers.

The objects of my invention are- First. To provide the means of feeding bagasse or crushed cane, or cornstalks, straw, hay, tan-bark, sawdust, or other fuel in such a manner that the fuel will be fed to the furnace in back of the dame on its way to the smoke-stack. By placing the fuel back of the re already in the furnace the f'uel is more readily ignited.

Second. To provide a means of drying such fuel on its way to the furnace, which is done by means of a chamber surrounded in whole or in part by the'heated air and smoke on its way to the chimney, or by the exhauststeam, or by both jointly.

Third. To provide a chamber surrounding in whole or in part the fuel-chamber in which the exhaust-steam from the engine escapes and furnishes heat to dry the fuel in the inner chamber, and it may also be used as a feedwater heater.

l attainthese objectsby the mechanism illustrated in the accompanying drawings, in which- Figure l is a perspective view of my improved generator, showing the fire-box, the cylindrical portion, a part ot' the uptake, and the fuel-passage and the feed-water heater attached,with pipes forleadin g the exhaust-steam to and from it. Fig. 2 is av perspective view, showing the parts above named and the pipes for conducting the feed-water to and from the heater; and Fig. 3 is a longitudinal sectional elevation, showing the arrangement of the parts.

Similar letters referto similar parts through out the several views.

In constructing a steam-generator with my improvements applied thereto any of the well- 'known forms ot' generators may be employed, and it maybe ot' any desired dimensions. rEhe generator, designated by the letter A in the drawings, is of the usual construction, except that it has in the front portion of its leg an aperture, B, which is located somewhat above the grate-bars vB', through which the fuel is passed into the furnace. In applying my iman attachment, C, which is secured by bolts or otherwise to the lower surface of the cylindrical portion thereof. rI his attachment is of such length as to cause it to extend from the front of the legs to or about to the front end of the smoke-box,its width being proportioned to the dimensions of the generator and to the kind of fuel to be burned, it heilig necessary that its size should beincreased when burning wet bagasse or straw beyond what it is when the fuel is dried before it is placed therein. The forward end of this attachment is provided with a door, C', through which the fuel is passed, a fork or any suitable implement being used for the purpose of inserting it. The upper surface of the passage may be the lower surface of the generator, and hence it will follow that considerable heat will be imparted to the fuel while it remains in the passage formed in it, the steam or vapor from which will be drawn into the fire-box, and will pass out through the tubes with the gases arising from the burning fuel. The side and bottom walls .of the attachment are double, as shown at G2 in Fig. 3, the space between which constitutes a chamber for the reception of exlPaustA-steam from the engine that may be connected with the generator, and for the reception ofthe feed- Water to be heated by such steam before it enters the generator. The pipes D are for conothe'r source to the heater, and the pipeD is for conducting any that remains nncondensed to the uptake or elsewhere. For conducting ducting steam from the engine, or from any.

provements to this form of generator I provide l IOO the interior of the generator, pipe E being a continuation of pipe E.

Having thus described my invention, what I claim, and desire to secure by Letters Patent7 1Q- 1. A fuel chamber or passage eonneeted to the generator, the upper part of said chainber being the lower surface of the generator, through which chamber the fuel is passed to the front ofthe fire-box, substantially as and for the purposes set forth.

2. The combined water-heater and fuel-passage C, constructed substantially as described, whereby it is made to serve the double funetion ofheating the feed-water and to some exi5' tent of drying the fuel previous to its entering the fire-box, as described.

Theeombination ofthe attael1mentG,eon tainingthe fuel-passage and feed-waterheater, with the cylindrical portion ot' a Stettin-genera zo tor7 substantially as and for the purpose set forth.

In testinion)v whereof` I atx my signature in presence of two witnesses.
